CONRAD F. LANCASTER, OF EAST LIVERPOOL, OHIO.

ILLUMINATED SIGN.

SPECIFICATION forming part of Letters Patent No. 738,332, datedSeptember 8, 1903.

Application filed October 20, 1902.

To all whom it may concern:

Be it known that I, CONRAD F. LANCASTER, a citizen of the United States,residing at East Liverpool, in the county of Oolumbiana and State ofOhio, have invented a new and useful Improvement in Illuminated Signs,of which improvement the following is a speciflcation.

My invention relates to illuminated signs;

of letter for such signs in which fewer lights will be used than are nowused.

Myinvention consists of a novelform of let-' ter hereinafter fullydescribed and claimed.

In the accompanying drawings like characters of reference refer to thesame parts throughout both figures.

Figure 1 is a plan view of a letter constructed according to my design.Fig. 2 is a The numeral 5 indicates the body of my letter, which isprovided with openings therethrough. Through these openings pass lamps6, preferably illuminated by electric light. The body 5 of my letterconsists of an outer portion 7, formed substantially U-shaped incross-section, lined internally with a glazed enameled surface 8. Bothbody portion and enameled surface project within the outline It isobvious thatthis enameled surface, being glazed, will act as a strongreflector of the light, and it is equally obvious that, by reason ofinwardly'projecting portions 9, the light will be diffused throughouttheentire letter in such manner as to illustrate the whole letter equally.

It will thus be seen that I have provided a novel form of letter forilluminating-signs in Serial No. 127,954. (No model.)

which the results heretofore specified are accomplished in an economicalmanner.

Minor changes may be made in my invention without materially affectingthe principles of the same, and I do not, therefore, desire to confinemyself to the exact form herein shown and described, but wish to includeall such as properly come within the scope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An illuminated sign, having a body formed of a frame substantiallyU-shaped in cross-section, said frame having lamp-receiving openings inthe base thereof, lamps provided therein,and inwardly-extending flangesformed integral with the upper edges of the walls of said frame, saidflanges adapted to reflect the light inwardly upon the frame,substantially as described. 4

2. Anilluminatedsign,comprisingaframe, substantially U-shaped incross-section, said frame being lined throughout with a reflectingmaterial, flanges formed at the outer ends of the frame, said flangesbent inwardly at right angles to the walls of the frame and adapted toreflect the light inwardly upon the frame, said frame havinglamp-openings in the base thereof, and lamps therein, substantially asdescribed.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.

CONRAD F. LANCASTER.

In presence of-- LOUIS MoEsER, S. B. Laws.
